This is a free ballistic calculator for use with Windows Excel and any pocket PC / Windows CE that has Excel installed.
Provided you input the right data to start, this is one of the most accurate calculators i have used. Using this in a PDA has scored me 1 shot hits on Groundhogs out to 460 yards with light little 223 40gr Vmax with my flat top AR.
The original spread sheet was by Ballistics programs and downloads (http://www.jacksonrifles.com/ballistics.htm)
Acknowledgment: Methods and formula used in this spreadsheet were developed by Prof. Arthur J Pejsa, Pejsa Rifle Ballistics: Art Pejsa's Rifle ballistics software and books (http://www.pejsa.com/)
Along with data and help from some of the guys that hang out on http://www.longrangehunting.com/forums
I have added many new things, like slope true range, range cards formatted to print 3.5x5 index cards, quick input screen for PDA's and more.
